Axial Deep Groove Ball B. FAG 51226

The FAG 51226 axial deep-groove ball bearing, with dimensions of 130 × 190 × 45 mm, reliably supports high axial forces from one direction.

The 51226 axial deep-groove ball bearing absorbs axial loads in one direction and supports the shaft axially against the housing. The FAG rolling bearing consists of a shaft ring, a housing ring and the ball and cage seat situated between them. As it is manufactured from standard rolling-element bearing steel 100Cr6, the component has proven its worth in mechanical and plant engineering at normal operating temperatures ranging from –30 to +150 degrees Celsius. The separate components allow for a systematic assembly of the discs one after the other onto the shaft.

What operating conditions does the 51226 axial deep-groove ball bearing require?

This bearing is primarily designed to accommodate single-sided axial loads in designs with vertical or horizontal shaft alignment. Typical applications include fixtures and axially loaded bearing arrangements where purely longitudinal forces occur without significant radial components. As the bearing is not angularly adjustable, the bearing arrangement requires precise alignment of the connecting parts. The contact surfaces in the housing and on the shaft must be perpendicular to the axis of rotation to prevent uneven loading of the rolling elements.

What is important in the single-acting design?

In the design, the precise positioning of the shaft and housing washers plays a central role. The shaft washer has a 130 mm bore with a tight fit, whilst the housing washer, with an outer diameter of 190 mm, remains radially free. An integrated sheet steel cage guides the rolling elements precisely with minimal friction. The bearing is manufactured to standard tolerance P0 or ABEC 1 and is fitted without additional shims. A sufficient minimum axial load during operation helps to ensure that the balls roll without any sliding motion.
